The cross-sectional descriptive study on color vision deficiency (CVD) among biomedical students carried out by Dohvoma et al1 is an interesting read. CVD is not tested in medical students in the UK, though it is routinely tested among those in India upon admission,2 as it is believed that misinterpretation of colored signs can lead to misdiagnosis. In the aforementioned study, 1.3% of the biomedical students were positively tested to be “color blind” through Ishihara’s plate test and Roth’s 28 hue test.1 The Farnsworth–Munsell 100 hue test also exists to diagnose CVD, though this is more time-consuming and expensive to carry out than Roth’s 28 hue test.3
